To all 'whom it may concern.-

Be it known that I, AUGUSTIN I. AMBLER, acitizen ofthe United States',residing at Washington, in the county of Washington and District ot'Columbia, have invented certain new and useful Improvements inGas-Generators; and I do hereby declare the following to be a full,clear, and exact description ot' the inven-V tion,'such as will enableothers Skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecitication.

My invention relates to improvements in gasgenerators which are designedfor producing gas from petroleum and other hydrocarbon oils, such gasbeing adapted for use as fuel in generating steam, heating furnaces ot'various kinds, and for warming buildings; and the objects of myimprovements are,\first, to provide a gas-generator constructed in sucha form as to adapt it for use'upon a locomotive-en-y gine; second, toprovide such'generator with a greater amount of heating-surface than hasbeen heretofore given in the same amount of space ,or with the sameweight of metal; third, to provide novel diaphragms for the interiorportion ot' the generator adapted for the passage of oil, steam, and gasfrom one portion of the device to another. I attain these objects bytheconstruction, combination, and Varran gement ofthe elements ofthegenerator illustrated in the accompanyingdrawings, in which- Figure l isan elevation of my improved generator, showing pipes for theintroduction of steam at different points, a pipe and branches lthereoffor conducting the gasfrom the generator, a pyrometer for showing thetemperature of the escaping gas, steam and gas gages for showing thepressure of the entering steam and of the escaping gas, and a glass gagefor showing the height of the oil in the generator. Fig. 2 is a verticalsectional elevation, showing the parts above enumerated, and in additiona pipe for admitting oil to the interior of the generator, the outer andinner cylinders, a covering of asbestus, pipes for the l admission ofsteam into the body ofthe oil -within the inner cylinder and for drawingoft lubricating-'oil and sediment, and the manner ot'- constructing thediaphragms which divide the inner cylinderl into compartments; and Fig.3 i-S an elevation showing the inner cylinder and the means of admittingsteam into the chambers within it., and also the steamspaces in itslower end for the passage ofsteam.

Similar letters refer to similar parts throughout the Severalviews.

In constructing gas-generators of the type.

metal, of any desired dimensions, and place upon the top thereof a domeor otherwise shaped structure capable of closing its upper end, saiddome or structure being riveted or bolted to the cylinder in such amanner as to prevent the passage of air or other substance between theparts. Y Upon the outer surface` of the cylinder A and its dome there isplaced a covering, A', of asbes'tus or other incombustible inaterial,which is a bad conductor of heat, and Outside of this acovering, A2, of wood or sheet metal, or both, for the purpose ofkeeping the nonconductin g material in place.

Within the cylinder A there is secured another cylinder and dome, B,also made of metal,

and of such dimensions as to leave a space, C,

suftciently broad for the circulatioxn of steam between the twocylinders. Y v Y v Within the interior cylinder there is placed a seriesof diaphragms, B2, which constitute a series of chambers for thereception of steam from the spacebetwcen the cylinders A and B, oblongor otherwise formed openingsB being formed inthe cylinder B, between.Said diaphragms, for itspassage, they being riveted to the cylinder soas to prevent the passage at the points where they are placed ot' theascending gases between them and the cylinder. This construction ofdiaphragme or chambers provides for two heating-surfaces upon each, andthus insures the prop er heating of the gas as it rises through theapertures. There may be any number of these chambers, and in order thatthe gas generated in the apparatus may rise freely to thc dome D in theupper portion of cylinder B, there is placed in each of the diaphragmsor chambers tubular staybolts B3, having passages through them for thegas as it ascends. These stay-bolts also serve to strengthen the platesB2 and to prevent the chambers from collapsing.

Between each of the chambers composed of the plates B2 B2 there is agas-chamber, D, which insures the contact of the gas with both of saidplates, and thus the vaporizing of any oil that may be carried up withthe ascendingr gas, as well as the thorough heating ot' such gas.

Near the bottom ofcylindcr B there is placed a flanged plate orl'iead,E,t`hrough which pass pipes E' E', through which steam isadmitted to the body of the oil, which is placed in said cylinder forthe purpose of vaporizing it. One of the pipes, E', may be used fordrawing olf the oil after it has been reduced to the requisite gravityto be used as a lubricant.

The lower end of the cylinder B is provided with corrugations or spacesF, for the passage ot' steam from the space between the two cylinders tothe under side of the plate E.

For the purpose of admitting oil into cylin der Baa pipe, G, isprovided, Awhich is to be connected to a reservoir of oil placed atasufcient height to cause'it to How into said cylinder by its owngravity, or to a pump or other forcing device which will feed the oil.In either case the quantity allowed to enter in a given period of timeis to be regulated. That portion otl pipe Gwhich is within the cylinderB is provided with apertures upon its under surface for the purpose ot'comminuting the oil as it enters, and for distributing it over aconsiderable portion of the heating-surface. If preferred, a rose-headmay be -placed upon the end of this pipe, and the distribution of theoil effected in that manner.

For the purpose of introducing steam, superheated or otherwise, into thebody of the as cending gas, a pipe, G', is used, which maybe connectedto any kind of a steam-superheater or to a generator, (the former beingpreferred,) and made to enter some distance into the interior cylinder,so as to cause the steam entering to be properly commingled with thegas, and thus constituteita hydrocarbon gas when ready for use.

In order that steam may be admitted into the space G between thecylinders A and B `'pipes G2 are placed in the outer cylinder, near its-bottom, their outerl ends being connected with the source of supply.The steam enter- 'ing through pipes G2 passes up in the space C andthence into the chambers between the .anged Aplates B2, and is thus madeto heat connecting them with a generator of steam placed in anyconvenient position.

For .the purpose of conducting the gas to the point where it is to beburned a T-shaped pipe is inserted in the upper dome, the verticalportion of which extends down into thc inner one, from which it receivesthe gas and conducts it to pipes H H, either or both of which may beused to conductit to the point where it is to be burned. A

As a convenient method of showing the temperature of the gas or vapor asit leaves the apparatus, there is placed upon the outlet-pipe apyrometer, I, which, by indicating the temperature thereof, enables theoperator to regulate the admission of steam in such quantities as toinsure the vaporization of all of the oil carried up by the ascendinggas bet'ore it leaves the apparatus. I also, for convenience, place aglass gage, J, upon the apparatus in any convenient position and connectit with the space occupied by the gas for the purpose of indicating thepressure thereof as it leaves the apparatus, thus enabling the operatorto prevent waste at thc burners by allowing too much pressure to obtainat that point. l also prefer to attach to the steam-space between thecylinders A and B a steam-gage, K, so that the pressure ot' steamtherein may at all times be known.

For the purpose ot' determining the height of the oil in the apparatusthere is placed upon the outside thereof a glass gage, L, of the usualconstruction, it being made to communicate with the space within theinterior cylinder, one of its ends being below the oil therein and theother above it, so that the oil always rises therein to the same heightthat it does in the cylinder, which height may be ascertained by lookingat the glass tube ofthe gage.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-
